Pools

 

No available pool members.

 

When all pool members are unavailable due to being disabled, forced offline, or down, the BIG-IP RST behavior varies slightly depending on the virtual server type. If the virtual server references a TCP profile (Standard virtual server type), the system allows the three-way TCP handshake to complete before sending the TCP RST to the client. If the virtual server references a FastL4 profile, the system sends a TCP RST packet in response to a connection attempt. The TCP RST packet is sent on the client side of the connection, and the source IP address of the reset is the relevant virtual server IP address.
